Answer 2

Answer:-

Ammonium sulphate

Explanation:-

Ammonium sulphate [(NH4)2SO4] is formed from a weak base, ammonium hydroxide (NH4OH), and a strong acid, sulphuric acid (H2SO4). On dissolving in water, (NH4)2SO4 hydrolyses to form more H+ ions than OH- ions. As the aqueous solution of the salt (NH4)2SO4is acidic, it turns blue litmus red.
